CLOTH-CUTTING OR LKE MACHINEQ SPECIFICATION forming part of Letters Patenta No. 668,(532, dated February 26, 1901.

Application filed September 14, 1900. Serial No. 30,028. (No model.)

To all whom it may concern:

Be it known that we, RICHARD AYRTON ENGLAND and HERBERT RoBERTs, subjects of the Queen of Great Britain and Ireland, re-

siding at Bin gley, in the count-y of York, England, have invented new and useful Improvements in Cloth-Cutting or Like Machines, of which the following is a specification.

Our invention relates to cloth-cutting and like machines, the object being to provide an appliance for taking up the slack edges of the fabric or adj usting the tension of the said fabric at any desired part. For this purpose we employ a counter-shaft mounted in any suit able manner over the draw-roller and suitably driven from any desired part of the machine. On this shaft are mounted two or more friction-rollers, which are adjustable as to their position on the shaft, so as to be adaptable for various widths of cloth, and are preferably covered with steel carding. The speed of the said counter-shaft may also be varied (according to the condition of the fabric under treatment) by means of suitable conepulleys.

In the accompanying drawings, Figure lis a partial end elevation of a cloth-cutting machinehavingourimprovementsapplied. Fig. 2 is a sectional end elevation of a cloth-cutting machine, showing such parts as are necessary to illustrate our invention. Fig. 3 is a front elevation of the friction-roller shaft and its bearings, one of the said friction-rollers being shown in section.

A is the counter-shaft, which is Suspended over the draw-roller B by adjustable arms C C from the frame D. On the said shaft A are mounted the friction-rollers E, preferably covered with steel carding F and adjusted by studs G. The said shaft A also carries a conepulley H, which is preferably driven from the draw-roller B by means of belts P J and intermediate shaft K with cone-pulley R; but the shaft A may be driven in any other approved manner, so that the friction-rollers and the draw-roller are revolved at different surface speeds. The belt P is a crossed belt, and the belt J is an open belt, so that the rollers E are revolved in the reverse direction from the roller B.

L is a shaft, and M represents toothed wheels which are part of mechanism for adjusting the' tension of the belt J, but which is not herein fully described or shown, as it is not an essential part of the present invention.

S is a guide-roller for bending the cloth partially around the roller B.

The edges or lists of the fabric N on passing between the draw-roller B and the adj ustable friction-rollers E are thus tightened to any required degree, according to the speed at which the counter-shaft A is run. By this means a perfectly even tension of the fabric at all parts may be obtained and the fabric is rendered less liable to being damaged during the cutting operation.

What we claim as our invention, and desire to secure by Letters Patent, is

In apparatus for equalizing the tension ou textile fabric, the combination, with a drawroller B, and a guide-roller S which bends the fabric partially around the draw-roller; of a counter-shaft A, adjustable arms C C provided with bearings for the counter-shaft, adj ustable friction-rollers E Secured on the counter-shaft at points opposite to where the tension of the fabric is to be changed, and driving devices for revolving the said draw-roller and the friction-rollers at different surface speeds, substantially as set forth.

In testimony-whereof we have signed our names to this specification in the presence of two subscribing witnesses.
